9.2-7 Binary data is transmitted by using a pulse y p(t) for 0 and a pulse p(t) for 1. Let y < 1. Find that the optimum receiver for this case is a filter matched to p(t) with a detection threshold as shown in Fig. P9.2-7. (a) Determine the error probability P of this receiver as a function of Eb/N if 0 and 1 are equiprobable. Figure P9.2-7 1=Th P(Tb-t) تمام Decision: 0 if r < threshold 1 if r > threshold (b) Find the optimum choice of y to minimize error probability Pb of this receiver for a fixed Eb if 0 and 1 are equiprobable.
